CAMERA.

Specification of Letters Patent. Patented M31'. 31, 1914,

Application led October 19, 1912. Serial No. 726,843.

To all whom it may concern Be it known that I, PAUL Dmrz, a subjectof the Emperor of Germany, residing at Brooklyn, in the county of Kings and State of New York, have invented .certain new and useful Improvements in Cameras, ot

which the following is a specification.

This invention relates to cameras, the object of the invention being to provide improved means for setting and holding the shutter against improper operation and in which also the shutterf cannot be operated after the exposure of the film to rexpose a previously exposed portion of a film, in which the exposed filmis automatically wound up as the new film is brought into position to be exposed, in which the feeding.

" of tlie film is uniform so that an excess of A film camera, with the casing open to expose the interior mechanism; Fig. 2 is a rear- 'view of the camera, the casing ofthe camera being 3open to show the internal mechanism, and the rear plate of the shutter casing 3 being broken away between the points where it is" attached to the upper and lower guide rolls G and 7 the film also'being'broken away more clearly to'illustrate the shutter mechanism; Fig. 3 is a side view of the shutter casing; Figf 4 is a side view of a part of the means for raising and holding the shutter in its proper position to be operated; Fig. 5 is a detail viewof a modified form of means for operatin one of the film rolls; and Fig. 6 is a detail view of the push button 17, illustrating in dotted lines the slot whereby said push button canv be moved into position to engage the end of the lever 11 or moved into position to engage both the levers 11 and 12.

Similar characters of reference indicate corresponding parts throughout the different figures vo the drawings.

In the present improvement the shutter is shown arranged in the rear of the lens,

but this is of no importance, as the shutter' may be-variously arranged in `front of the plate or film, such relocation simply requiring the proportions of the levers to be changed. In the present 4improvement a perforated film is used.

The present improvement, in the `preferred form thereof, will of Course include a casing 1 for supporting the several mechamsmsand a' suitablelens 2,.a shutter carrying casing 3, which is suitably supported f by the casmg 1;/in the present instance by the walls 3% which support the lens 2, and suitable film carrying and guiding means, which in the present instance comprises a film carrying rollA: shown herein as located at one end of the camera, the film 5 of which, which may b e of any desired length to contain six, twelve, thirty or more pictures as may be preferred, is guided. over a guide roll 6 at one end ofL the shutter carrying casing 3 to a similar guide-roll 7.at the other end of the casing and then to a takeup roll 8, to which one end of the film is attached in any of the, usual ways, the film being drawn behind the shutter casing passing an exposed opening 9. The guide rolls 6 and v'' are carried by arms and 7 y respectively, the inner ends of which are attached to the rear plate of the shutter casing. In the present instance the film 'is shown provided with perforations l0, by means of which it may be fed.

Any suitable form of shutter mechanism may be used which is well known in the art,

and therefore only aA brief description thereof is necessary so far as the general construction of this shutter mechanism is concerned. I'

In the present instance the casing 3 car ries the two part shutter, which may consist. of two sliding members or plates a and Z) spring actuated in the usual manner. These members or plates may be held in their operative position for release by a pair of levers 11 and 12, the lever vl1 having a hook 13 for engaging a pin 14 carried by one of the members or plates, as b, and the lever 12 having a projection or shoulder 15 for 'engaging the pin/16 of the other member lor plate, as a, the levers being operated by a suitable plunger or push button I7, which is adjustably supported by pivoting a depending plate thereof on the outside of one side wall of the casing l with a part of the button extending through a slot in such casing wall, so as to engage one or both of the levers as occasion may require, this being one of the usual ways of operating' shut- 11o ters of this character and therefore but -a brief description is deemed necessary. 'As hereinbefore stated, the shutter casing 3 is supported by the side walls 31 forming the casing for the lens 2, and these side walls 31 form a partof'the main casing or camera box. The shutter casing simply comprises two sides, as shown at 3, and a -front and rear plate attached thereto, and between which plates the' `thin shutter members or plates a and Z) are supported for sliding movement. The shutter member a; is located in the rear of the member b, considering the top 0f the sheet of drawings as the front of the camera when .the sheet is turned on its side, and carries, as hereinbefore stated, a pin 16 for engagement with the hook 1 5 ofthe lever 12. The other shutter member b, which, as hereinbefore stated, has thel pin 14 for engagement with thefhook 13 of the lever 11, is provided' with the pins 20 hereinafter 'ref'erred to. At the lower ends of the shutter members the member b, which carries the pins 20 hereinafter referred to, has a projection c which engages the edge of a little recess l of member a, so that when the shutter member b is raised in the manner hereinafter described, through the medium of the pins 20 thereof, it will also raise the shutter member a; in other words, they will both be raised together against the tension of the springs e and f, ebeing secured at one end to the shutter member b and f at one end to the shutter member a, while the opposite ends are secured to the casing and serve to p ull the shutter` members downwardly when released. The lever 12with its hook 1 3, holds both shutter members in their raised position, when in engagement that it .will engage both the upper ends of the levers 12 and 11, in consequence of which, when the push button 17 is moved in-' wapdly' it engages the lever 11 yand releases the hookedend thereof from the pin 14, whereupon. the shutter member b is, by reason` o f its spring, Vpulled downward,- but owing to the form of the hook portion 15 of the lever 12 and tothe fact that this lever 12 extends at its upper end somewhat be-l yond the lever 11, this same inward move-` couse releases the lever 12 and the' hook thereof is withdrawn from the pin 16 and the shutter member a then follows to close the usual exposure opening. It will of course be understood that these levers 11 and 12 are controlled by springs usually located at the top thereof. In this form of shutter mechanism, however, when after an exposure the sliding shutters have been shifted into their raised position in readiness to be released in the manner hereinbefore described there is nothing to prevent the operation of the button 17 and thus operate the shutters lmproperly to rexpose the previously exposed film before a new film has been properly positioned, and one of the features of the present improvement is the provision` of means which will prevent the limproper operation of the shutter member b. For this purpose the shutter is provided with projections or pins 20,' although one will be sufficient if preferred, one at each side thereof, lprojecting through elongated slots 21 in the sides of the shutter casing 3, these pins coperating with the means for 'raising the shutters into their proper position to be released by the push button 17 hereinbefore described.

Preferably located on each side of the shutter casing is a slotted shutter operating bar 22, see Fig 4, into lthe slo-ts 23 of which headed studs er screws 25 project for guiding these bars. rfhese studs are carried by the sides of the casing 3. Each of these slotted bars is provided with a notch or bifurcation 27 at its upper end for engaging the pins 20 ofthe shutter member b and thereby raise both shutter members into their highest position. For shifting these slotted side bars the shutter casing is provided with projections 28 carrying a rock 'shaft 29 having crank arms 30 linked to the slotted side bars by links 31, and this rock shaft projects through the casing 1 and is providedwith a crank 32 for rocking it, whereby the slotted side bars will be raised and lowered by the handle. It will thus be observed that as the slottedk side bars are raised when the shutter is in its lowest position, having been drawn into that position same against being released by its push buti tonq17 or other operating means, so that until this handle 32 hasl been started downward to vcarry the slotted side bars downward land awa-y from the vpins 20 it is not possible to operate the shutter. I

Carried by the slotted side bars is a lm operating device, which in the present instance comprises a pair-of hooked armsl 35 carriedA by 'a swinging shaft or member 36 supported'on ears 37 of the slotted side bars 22 and being yieldingly held a einst the film by means of a sprin 38. lT us as the slotted side bars are raised these hooked film afctuatingmembers 35 are raised into position to engage perforations of the film, and as the handle is lowered to lower theside bars these hooked members will be carried downward andfso draw downward a portion of the lm from the roller 4. The film as:

it is drawn downward in the mannerl set forth is automaticall wound upon the roller shown by dotted lines, arid therefore they,

together with such 'parts of the film rolls 4 and 8 would have to be shown in dotted lines, have been .1 omitted to simplify the illustration; The flanges of disks 4 and 8 are clamped in position by means of k-nurled nuts 4 and 8 respectively, and these flanges 4Y and 8', together with the rollers 4 and'8, are mounted upon fixed shafts 60 and carried by one of the walls of the camera box and are rotatable on these shafts, which have threaded outer ends for the reception of the knurled nuts 4 and 8". The takeup roll 8, however, is carried by a sleeve 71, it being tight thereon or 'keyed thereto, and this sleeve l71, (see Fig. 1), is rotatable upon v the shaft 70\and at the inner end has one of the flanges 8 secured thereto or made as a part thereof, the other-Harige, or that one adjacent to the knurled nut 8, of course being removable `to permit the lmroll 8 to be removed from its sleeve 71. Between this fixed -langeand the 'meansabout to be de-v scribed forjrotating-this take-up. roll some .suitable frictional engaging means is located. In practice a flat spring may be, and is, used, it being` carried by a wheel 73, but

` in the present instance a space blockA 72 is shown, and by means of the knurled nut 8 this space block is maintained in tight frictional engagementwith one of the disks8, it being carried by the wheel 73, whereby on the 'rotation of this wheel ,7 3 the take-'up roll will be rotated, but such take-up roll' per mitted to slip as the roll v'of film gradually increases in diameter. Forv rotating this take-up roll thevwheel 73 is provided with, a series of pins 40 adapted to be engaged by a tooth 41 carried by an operatingbar 42 pivotallv secured at one. end to the crank arm 1, film-carrying roll 4 upright or at the top of the camera in the manner hereinbefore described this bar, which is'held in engagement 'vith the pins of the wheel 73 by 'means of a spring 43, will engagey one of the 'pins 40 of Stich wheel and *rotateI it the required distdnce in a manner which will be readily un'- "drstood, and this will, by means of the frictional engagement-hereinbefore referred to, rotate^the take-up-roll, which frictional engagementvwill permit the roll to slip when necessary. Thus, as the handle is raised the Shutter members are lifted into position to f lhave their pins 14 and 1x6 engaged by the hooked levers and in this position'shouldV the push button 17 be operated no exposure will take place. 'As the handle is 4pulled downward into its full line or normal position shown in Fig. 2 the previously exposed film 1s carried downward and wound automatically upon the take-up roll and the forked slde bars carried away from the pins 20 of 90 the shutter member b, so 'as to release the same and enable themto be operated in thel usual manner by the button 17.

From the foregoing it will be observed Vthat so lpng as the handle is in one posit-ion, as for instance its raised position, vthe premature exposure of a film is impossible. As the purpose of grasping the handle when it 1s in its raised 'position is t-o return it, that is to draw it to another position, as for instance downward to its full extent, it follows t that it would be fully lowered when once it was grasped for the purpose of lowering it,4 so that there would be but little opportunity to open the shutter during the lowering operation of they handle. If, however. such action should take place it will be obvious from the fore-going that as the handle is lowered the prev1ously exposedl film 4is shifted, and as the Vshutter cannot be' fully 11o opened until the handle is completely lowered, the amount of such opening of the shutter corresponding with the move-ment of the handle, it follows that should the shutter be accidentallytripped during the lowering `of the handle it would only expose a new portion of the film and would not expose a previously exposed portion of alm. So that, as stated herein, while the'handle is in its raised position the shutter cannot be 12o opened at all, and thereforethe exposure of a previously exposed film is not possible.

It willv be understood that instead of providing the particular means shpwn forrotating the take-up drum or roll the take-up roll actuating wheel could be provided' with teeth 45 instead of pins 40 andthe'bar 42 could be provided with a rack 46 instead of teeth 41 for rot-ating it, as shown in Fig. 5.
